To all whom it may concern:

Be it known that I, PETER WEBER, a ci ti zen of the United, States, anda resident of Orange,-,jn-the county of Essex and State of New Jersey,have invented certain'new and useful Im rovements in Phonographs, ofwhich the Following is a description.

My invention relates to phonographs of the type wherein'the sound box iscarried on atraveling'carri'age to which a progressive movement isimparted by means of a rotatmg feed screw, so that the reproducerorreco'rderstylus 'traces a spiral path with respect to the recordsurface. It has been the to, rovidea feed screw of fine pitch which wiladvance the traveling carriagea distance of one one hundredth of an inchfor each revolution of the mandrel. More recently, howevcliy; it hasbeen found possible to manufacture-a sound-record in which therecordfiroo ve has two hundred turns or threads to t e inch, so

that it is desirable to provide a phonogra h' in which the feed of thecarriage will be suit of'this description. In view of the fact,"however, that there are already thousands of phonographs in use inw'h1ch the feed screw advances the carriage one one-hundredth of an inchper mandrel revolution, and a vast number of records are also in usehaving a pitch of one one-hundredth of an inch, it is desirable toprovide means which may readil be applied to such phonographs where ythe feed screw may be driven at one-half the speed at which it has beenheretofore driven-,such means also permittin the drivin speed, so t atthe phonograph can be used interchangeably with sound records havingeither one hundred or two hundred threads per inch, and my'invention hasfor its object the provision of interchangeable means of this characterwhich may be readily applied to a phonograph and in which, when so applied; the parts may be readily shifted with respect to each other; soas to drive the feed screw-at the desired rate of speed. Reference .ishereby made to the accom panying drawings, of whiclis Figure 1 is a lanview showing a portion of a phonograp constructed inaccordance of'thesame, and

-of the feed screw at its usua of a well-known form and comprises-a base1, formed with anupright2 havinga center 3 which supports one end of themandrel shaft 4, which carries the mandrel5. A. drive pulley 5 issecured to the shaft 4, and is adapted to receive the drivin belt fromthe motor. A drive gear 6 is xed to the ,shaft 4. Parallel tdthe mandrelshaft 4 and" in the rear thereof is the-feed screw shaft 7, one end ofwhich is sup orted upon the pivot pin or center 8, carrie by the upright2. A gear 9 is fixed to the shaft 7 and tably mounted-on a movable pin11 which is supported in a boss formed on the upri ht 2. The gear '10,when in the position 0 Fig. 1, is in 'engagem.e'ntwith the gears 6 and9, and the sha shaft 4 through thegears 6, 10 and 9 which areroportioned for driving'the'snatt i and fe mg the'sound- .box' carriage21'Rat the proper speed for g'perating-upon asound record, t e pitch owhich s onesone-hundredth of an i'nch.- The pin 11 is; provided with aknob or head 12 ,for moving the same longitudinally therebi fromengagement wit the gears 6 an '9, A set screw 22 may be provided forholding the pin 11 in any desiredpo'sition;

In order that the shaft Z may be driven at a speed suitable foroperating upon a record having two hundred threads per inch, -I providea frame or en port 1 3 which is mounted upon; the end" o the .p1n 8WlHCh 'roj ects beyond the upright 2, i said frame eing angularlyadjustable upon said pin and adapted to be clamped in'a .fixed os 1-tion bymeans of a set screw 14. I118 frame carries agear'train'composed. of spur gears 15,16, 17 and 18. The frame 13 may be moved in adirection parallel with the axis of'the shaft 7 so as to bring the gear18 into and out of engagement withthe gear i). When the gear 10 is inthe position of Fig. 1 for driving the shaft'T at a speed for 0 9eratingupon records having 'one hun red threads tothe inch, the frame 13 willpreferabl occupy the position shown in Flgs. 1 an 2, although, ofcourse, it could occupy a position in which the gear l8 engages the ear9, provided the gear 15,1s not 1n engageeve the ,,wou d be is adapted tobedri'ven by a gear 10 rotat 7 isldriven from the removing the car 10mentqwith thegear 6; In thiscase, how-Q ars carried by the. frame. 1 3dgriven as idlers, thusintroducing 1 Lil unnecessary friction. When theframe 13 is adjusted upon the pin 8 from the position shown in fulllines, Fig. 2, to the position in dicated in dotted lines, the gear 15will be brought into engagement with the drivin gear 6, and thegearhaving been moved out of engagement therewith, the shaft? will be driventhrough the gear train 6, 15, 16, 17, 18 and ,9, and these gears are soproportioned that the speed of the shaft 7 will be suitable for feedingthe sound box carriage with respect to a sound. record having twohundred threads per inch. All that is necessary to-convert the machineinto one suitable for a record of one hundred threads to the inch is tomove the frame lfilinto the osition shown in the drawing, securing it ythe set screw 14, and then move the gear 10 into the osition shown,which operation can be readi y understood and performed by the ordinaryuser of a phonograph. The frame 13 is preferably provided with aprojecting foot 19 which is adapted to restupon the upper edge of theupright 2 when the frame 13 is in the position shown in dotted lines,Fig. 2, thereby supporting the frame 13 in its operative position.

The honograph shown in Figs. 3 and 4 is simi ar in its general featuresto that of Figs. 1 and 2. The guide rod 20- in the machine of Figs. 3and 4 is situated above the shaft 7 and upon its outer end may besecured the frame 13, which is similar to the frame 13 and which carriesthe gear train 15, 16, 17 and 18 adapted to operatively connect thegears 6 and 9 carried by the shafts 4 and 7. The frame 13 has a foot 19adapted to rest upon the upright 2, and a set screw 14 is provided forholding the frame 13 in its inoperative position as shown in full lines,Fig}. In this position the gear 18 will necessarily be out of engagement with the gear 9, and it is therefore unnecessary to move the frame13 in a direction parallel to the axis of the shaft 7'. In all otherrespects the device of Figs. 3 and 4 is the same as that of Figs. land2.

It will be noted that in my invention the frame of an existing type ofphonograph is made use of unchanged, the only changes which must be madeto the same to adapt the machine to operate on one hundred and twohundred thread records interchangeably, being the substitution of thesliding stud 11 for the fixed stud for carrying the interme-- diate gear10 of the existing gear train between the mandrel shaft and the feedscrew shaft, this stud 11, of course, being lengthened, and thesubstitution of the prolonged center 8 for the feed screw shaft for theshort center for the feed screw shaft found in the existing one hundredthread machine. On the prolongation of the center 8 is placed thesupporting frame 13 carrying the gear train as above described.
